uh oh...2800z doesnt haf this kinda settings, i switched off the flash, and set EV to -1.5, (if +1.5 juz see a blob of white light) the only way i can speed up the shutter speed is if i on the flash..hmzmzmzm...oh and full 6x zoom.
As the light from the moon is the reflected light from the sun, moon-shooting is just like shooting something under daylight - EV 15.
If the camera has manual functions, you can use the Sunny 16 rule, i.e. if using ISO 50, set the shutter speed to 1/50 sec and the aperture to f/16. If you are using a very long focal length to capture as big the full moon on a frame, a shutter speed of 1/400 sec (to minimise handshake) and an aperture of f/5.6 (there is no need for a deep depth of field if shooting just the full moon) for ISO 50 is the equivilent.
